Shader Modification
When analysing a trace, it may be required to modify a shader program in order to test new behaviour
in image output and performance. To modify a shader, perform the following:
1.
2.
3.
Repeat the procedure for shader inspection (see Section 3.10.1).
Make modifications to the shader program. If the program compiles successfully, the Apply
button (Figure 34a) will become active to allow saving changes made to the shader.
Save changes by clicking the Apply button. For tracking purposes, the modified shader
program is displayed in the Modifications window (Figure 35).
Note: Shader modification can be removed by unchecking the modified shader and clicking on Apply
Changes from the Modifications window (Figure 35). Alternatively, use the Reset button in
the Source tab of the Object Data Viewer window (Figure 34b).
